Help me diagnose this sound...

[Spoolin98]

Hey guys/girls,
I need help diagnosing this motor knock/slap/tap. It's coming from the head, and I'm pretty sure the head is going to need to be pulled. I just want to get an idea of what I'm getting myself into. Thanks for the feedback in advance.

Could of jumpped a t-belt tooth. Happened to me once but luckily I shut it down immediately after. Reset the belt and compression was normal.

May want to give this a try as may not need to pull the head after all

Hard to tell specifically from the sound byte, but it didn't seem to be skipping or sputtering. Oil pressure ok?
Yeah I'd do a compression check and align the timing first...
But it does sound like you got a lifter or valve banging around.
I wouldn't drive it too much like that, if it falls out, you might have to do a whole motor...
Pull the plug wires and see if it goes away...
At least it might tell you what cylinder..

Thanks for the advice guys, I'll give the compression test a try. Oil pressure is normal. Unfortunately my brother drove the car for a couple miles with it tapping like that, hopefully everything is ok, I guess ill have to wait and see. I'll keep you guys posted, thanks again.

Depends on what it sounds like. To me, it seems like it could be a dry lifter or so. This happened to my old 90 gst when I put 20W-50 in it. Floated lifters twice before I figured out what it was. I would take it to someone who knows what a floated llfter sounds like and ask them. If that is the case, the head can stay on it.
